"Meta recently conceded that in-app behavioral advertising in the EU can no longer be opt-in by default, marking the end of an era. The regulators won, at least for now."

"Opt-in by default". In other words, "opt-out". Is this some wordplay designed to "comply" with regulations against opt-out.

Yes, it's opt-in, with the opt-in box already checked to save people the trouble.

Sounds like a so-called "dark pattern".
